Let me preface this by saying that much of what I trust about IMS related issues comes from posts by JFP and Mike Focke. If you have a lot of concern about the IMS bearing, get the "Solution" and be done. If you are replacing a bearing that has already exceeded 100k miles as maintenance and aren't constantly listening for the impending failure, the Pelican kit is probably a 'good enough' replacement. The bearing is same as stock, but it does have an improved center bolt.
My guess it that if it has made it this far on the original, the shaft is balanced and true enough to run another factory bearing until your next clutch change.
Me? ...I have a 99 on the original, one with an LN Ceramic, an '01 with the Pelican, and I think I'll put the solution in my '04 next year. How's that for decisiveness.
